Subgroup ($H$) information

Description:$C_{14}\wr C_2$
Order: \(392\)\(\medspace = 2^{3} \cdot 7^{2} \)
Index: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Exponent: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Generators: $ad^{7}f^{6}, e^{2}f^{12}, e^{7}f^{7}, f^{7}, d^{2}e^{6}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Ambient group ($G$) information

Description: $(C_7\times C_{14}^2):S_4$
Order: \(32928\)\(\medspace = 2^{5} \cdot 3 \cdot 7^{3} \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$4$

The ambient group is nonabelian and monomial (hence solvable).

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_7^3.C_2^4.C_6^2.C_2$
$\operatorname{Aut}(H)$ $D_{14}:C_6^2$, of order \(1008\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 7 \)
$W$$D_{14}$, of order \(28\)\(\medspace = 2^{2} \cdot 7 \)
